ABRAM E. SMITH, F BROOKLYN, NEW YORK.

RAILROAD TANK-CAR.

Application filed December 6, 1915. Serial ITo. 65,210.

To all whom 2'25 may concern:

Be it known that 1, Anna): E. SMITH, a

itizen of the United States, residing at New York city, borough ofBrooklyn, in the countyof Kings and State of New York, have inventedcertain new and useful Tmprovements in Railroad Tank-Cars, of which thefollowing is a specification.

.My invention relates more particularly to railroad tank cars, though itmay be used in connection with other types of cars. I will describe arailroad tank car embodying my invention and then point out the novelfeatures in claims. 7

in the accompanying drawings Figure 1 is aside elevation of a railroadtank car embodying my invention. Fig. 2 is'an end elevation of the carshownin Fig. 1, but partly in double vertical section, the section beingtaken on the line 1-1 of Fig. 1 and looking in both directions of thearrows, the center anchor of Fig. 1 being shown to the left of thevertical center line onFig. ,2, and the end fastening of Fig.1 beingshown at the right of the center line on Fig. 2, the center anchor beingshown as viewed from the right of 1 and the end fastening as viewed fromthe left of Fig. 1. Fig. 3 is a side elevation of a railroad tank caralso embodying my invention and showing a fastening device at or nearthe end of a car body. Fig. 4.- is an end elevation of the car shown inFig. 3, but partly in double vertical section, the section to the leftof the vertical line on Fig. 4; being taken on the line a; and the.section to the right of said vertical line being taken on the line 4: ofFig. 3 and looking in the direction of the arrows. Fig. 5 is a detailperspective view of a form offastening device embody ing my inventionwhich is used in Figs. 1 to 1, inclusive. Fig. 6 is a detail perspectiveview of a means which 1 preferably employ for preventing vertical andsidewise move- .1 ments of the car body relatively to the underframe,but permitting of longitudinal expansion of the car body when thefastening device of Fig. 5 is used on one of the tank cars, asillustrated in Fig. 3.

Similar letters of reference designate corresponding parts in all of thefigures.

1 designates an underframe which is suitably supported on wheels 2. Theunderframe 1, as here shown, comprises two longitudinal sills 3, a,which are suitably joined together, as, for example, by top andbottoinplates' 5, 6, which extend the entire 7 length of the sills, thusm'aintaininga uniform strength of the underframe throughout the entirelength thereof.

6 designates a car-body of any desired. form. As here shown, the body 6'is'inj the.

form of' a tank which may be of any suitable construction well known inthe art. The tank may also be provlded with heating apparatu's and aninlet and outlet for itscontents.

Referring now more particularly to Figs. 1 and 2, the body 6'is"supp'orted on the underfraine 1, near the ends thereof, in sad dies 7,and the body 6 is detachablysecured to the saddles 7 by means ofnuts'and'bolts 8 which pass through flanges 9 carried by the saddles 7and flanges 10 of angle iron which are riveted to the body 6.' Theopenings'in the flanges 9 and 10, throughwhich the bolts pass, areelongated so as to permit of longitudinal expansion of the body 6. Thepurposeof the above-described connection is also to'prevent vertical andsidewise movement of the body relatively tothe underfraine. This form ofconnection is set forth in Patent No. 1,100,405, granted to me June 16,191 1. Other means for preventing relative vertical and sidewisemovements between, the. tank and underframe may be pro vided,providedsuch means will permit of longitudinal expansion of the body 6.

In Fig. 1 the body 6 is connected with the underframe by the device oranchor shown in detail in Fig. 5 at about the'niiddle of the body 6..The device'or anchor for making this connection comprises "a' part 11connected to the. bot y 6, as here shown by rivets 11 and a part 12connected to the underframe, as here shown by rivets 12, and'bolts 13for uniting the parts 11 and 12. The parts 11 and 12 may be castings ofsteel or other suitable metal. The part 11 is provided with a series ofribs or projections 11 suitably spaced apart, which interengage with aseries of .ribs or projec- -tions 12 provided on the part 12. Theprojections 11f and 12 are provided with openings 11 and 12 whichregister, when the car is on the underframe, and through which the bolts13 pass, each bolt being held in its openings by means of a nut 13. Thebearing surface of the ribs or projections 11*, 12, as well as theirshearing value, is increased by extending them beyond the frame. Thecenter of gravity of the car is also lowered by having the ribs extendbeyond the underframe so that the bolts 13 may be inserted as low aspossible relatively to the top of the underframe. The bolts 13 are usedonly to prevent vertical movement of the body 6 relatively to theunderframe.

Referring now to Figs. 3, and 4, the fastening device or anchor of Fig.5 is placed at one end of the body 6, as shown in Fig. 3, and the meansshown in Fig. 6 is employedat the other end of the body. These means(Fig. 6) comprise a part 15 connected with the body 6, as here shown byrivets 15 a part 16 connected with the underframe, as here shownbyrivets 16 and one or more bolts 17, each provided with a nut 17, whichextend through openings 15 and 16 which register when the car is uponthe underframe. The parts 15 and 16 may be castings of steel or anyother suitable metal. The part 15 is provided with one or more ribs orprojections 15 which interengage with ribs or flanges 16 carried by thepart 16. The openings 15 are preferably elongated to permit oflongitudinal expansion of the body 6.

The two devices at the ends of the body in Fig. 8 also prevent verticaland lateral movement of the body relatively to the underframe.

Having thus described my invention, what I claim as new is 1. Thecombination in a railroad car, of a car-body, an under-frame, and afastening between the underframe and body, said fas tening comprising apart connected with the car-body and provided with one or more ribs orprojections, a part carried by the underframe and having ribs whichinterengage with the said ribs or projections, and bolts which passthrough registering openings in the said two parts.

2. The combination in a tank car, of a tank, an underframe, and afastening between the tank and underframe comprising a part carried bythe tank having ribs or projections extending transversely of the tank,a part carried by the underframe and having ribs or projectionsextending transversely of the underframe over the top ther of, whichribs or projections interengage with the ribs or projections of the partcarried by the tank, and bolts passing through the said ribs orprojections.

3. The combination in a tank car, of a tank, an underframe, and afastening between the tank and underframe comprising a part carried bythe tank having ribs or projections extending transversely of the tank,a part carried by the underframe and having ribs or projectionsextending transversely of the underframe over the top thereof, whichribs or projections interengage with the ribs or projections of the partcarried by the tank, and bolts passing through the said ribs orprojections at the end portions of the ribs or projections.

4. The combination in a tank car, of a tank body, an underframeincluding a central longitudinal sill, and an anchor for se curing thetank body to said sill, said anchor comprising two series of projectionssecured respectively to the sill on opposite sides thereof, andprojecting laterally therefrom, said series extending longitudinally ofthe sill, and two series of projections secured to the tank on oppositesides of the sill and extending downwardly from the tank, each series oftank projections extending longitudinally of the sill and interengagingwith the series of projections on the sill, and a fastening boltsecuring each series of tank projections to the sill projections andextending longitudinally of the sill.

5. The combination in a tank car, of a tank body, an underframeincluding a central longitudinal sill, and a fastening be tween saidtank body and the center sill comprising a part connected to the tankbody, and a part connected to the underframe, the first-named partconsisting of two series of projections each extending longitudinally ofthe tank body and located on opposite sides of the center sill, and thelast-named part consisting of two series of projections each extendinglongitudinally of the center sill and inter-engaging with theprojections on the tank body and a bolt extending longitudinally of thecenter sill and securing the projections on the center sill to theprojections on the tank body.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.
